  • Patent number: 10704399
    Abstract: A hot gas path component of an industrial machine includes a cooling pathway. The component includes a body including an outer surface; a thermal barrier coating (TBC) over the outer surface, the TBC exposed to a working fluid having a high temperature; and an internal cooling circuit in the body carrying a cooling medium. A cooling pathway is in the body and in fluid communication with the internal cooling circuit. The cooling pathway includes a terminating end in the body and a length extending along and spaced internally from the outer surface by a first spacing. In response to a spall in the TBC occurring at a location over the cooling pathway and the high temperature reaching or exceeding a predetermined temperature of the body, the cooling pathway opens at the location through the first spacing to allow a flow of the cooling medium therethrough.

  • Publication number: 20190253767
    Abstract: A system for remotely controlling client recording and storage behavior schedules the recording, storing, and deleting of multimedia content on a client system storage device. The viewer may request that certain content be captured. Capture requests also allow the service to determine content to be recorded by the client system in the same manner that a viewer requests that certain content are recorded but are more powerful than what a viewer can request. Recording requests for a capture request can preempt viewer requests or be entered at the same or lower priority as a viewer request. Capture requests can adjust all aspects of a recording request and affect the capture request itself. Client system operational functionality are also manipulated by the service using capture requests.
